This means that pressure leads to a precise separation exactly between stone grain and binder filling. In this way, reliable granulations of < 11 to < 22 mm can be produced. Due to limited crushing space geometry the amount of oversized grain is less than 1%.

Crushed stone is produced by crushing quarry rock, boul-ders, cobbles, or large-size gravel. Crushed air-cooled blast-furnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the pit or plant. Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected.

So, compressive strength is the highest load per unit area borne by the stone without giving in. A higher compressive strength between1,800 psi (12.45 MPa) and 19,000 psi (131 MPa) means the stone can endure an upper crushing load. Dry or wet conditions as per load determine the compressive strength of the stone. Bending strength test.

Crushed Stone: The Unsung Mineral Hero: Crushed stone is often looked upon as one of the lowliest of commodities, however it is used for such a wide variety of purposes in so many industries that it should be elevated to a position of distinction.
